Cooling Systems’ Auxiliary Role in Water Well Drilling Rig Fault Diagnosis

Abnormal water temp and engine faults: Sudden high temp may mean leaking cylinder liners or bad thermostats. Low temp could signal stuck thermostats or blocked radiators. A rig’s temp spiked; white exhaust showed a leaking liner—repair saved the engine.

Abnormal hydraulic oil temp and system faults: High oil temp may come from worn pumps or faulty relief valves. Low temp could mean failed bypass valves. A rig’s oil hit 65℃; a worn pump was the cause—replacement fixed it.

Flow and pressure anomalies: Reduced flow may mean worn pumps or blocked pipes. High pressure could signal blocked radiators or bad valves. A rig’s cooling pressure spiked; scale-clogged radiator—cleaning restored normalcy.
